TIME AND FUEL CONSUMPTION FOR HIGHWAY USER BENEFIT STUDIES

TIME SAVINGS AND FUEL SAVINGS ARE TWO OF THE MORE IMPORTANT BENEFITS THAT ACCRUE TO USERS THROUGH HIGHWAY IMPROVEMENT. USER TIME SAVINGS RESULT WHENEVER HIGHWAY IMPROVEMENTS REDUCE TRAVEL DISTANCE, PERMIT HIGHER SPEEDS, OR REDUCE THE FREQUENCY OF STOP-AND-GO AND SLOWDOWN MANEUVERS. USER FUEL SAVINGS ACCRUE WHEN IMPROVEMENTS REDUCE TRAVEL DISTANCE, MITIGATE ANY OF THE RESISTANCES ENCOUNTERED BY MOVING VEHICLES, OR REDUCE THE FREQUENCY OF STOP-AND-GO AND SLOWDOWN OPERATIONS. THE REDUCTION OF TRAVEL DISTANCE, FREQUENCY STOP-AND-GO AND SLOWDOWN EVENTS, AND RESISTANCE TO MOVEMENT, AS WELL AS INCREASE IN SPEED, RESULTING FROM HIGHWAY IMPROVEMENTS CAN BE ESTIMATED FROM DATA AVAILABLE IN PUBLISHED REPORTS AND BY MAKING TRAFFIC STUDIES AT LOCATIONS WHERE IMPROVEMENTS ARE PLANNED. HOWEVER, INFORMATION ON CURRENT SAVINGS IN TIME AND FUEL USE ASSOCIATED WITH THESE EFFECTS OF HIGHWAY IMPROVEMENTS HAVE BEEN INSUFFICIENT FOR BENEFIT ANALYSES. DURING THE SUMMER OF 1959 THE BUREAU OF PUBLIC ROADS CONDUCTED A STUDY OF PASSENGER CARS AND SINGLE-UNIT TRUCKS TO DETERMINE THE EFFECT OF VARIATION OF PAVEMENT SURFACE TYPE AND OPERATING SPEEDS ON FUEL CONSUMPTION, AND THE EFFECT OF THE ELIMINATION OF BOTH A STOP-AND-GO AND A SLOWDOWN OPERATION ON FUEL AND TIME CONSUMPTION AT VARIOUS OPERATING SPEEDS. THIS STUDY ALSO INCLUDED THE DETERMINATION OF THE FUEL CONSUMED WHILE VEHICLES ARE STOPPED WITH ENGINE IDLING. THE RESULTS OF THIS INVESTIGATION ARE PRESENTED IN THIS REPORT IN GRAPHICAL AND TABULAR FORM. /AUTHOR/
